An Introduction To The IoT

What is the Internet of Things (IoT)? One definition is that it is a network of physical objects (or ‘things’), each endowed with electronics, software, sensors and connectivity that will together enable it to achieve greater value and service by exchanging data with the manufacturer, operator and / or other connected devices. To achieve this, every 'thing' - which could be an LED light source or luminaire, or thermostat, for example - must be uniquely identifiable through its embedded computing system, yet it must also be able to interoperate within the existing Internet infrastructure. Such devices already exist. Typically, IoT covers many protocols, domains and applications, and should offer advanced connectivity of devices, systems, and services that goes beyond machine-to-machine (M2M) communications. The interconnection of all such embedded devices will also help enable advanced applications such as smart grids. Not only that, with a huge increase in connected devices expected within a very few years, switched-on electrical contractors and installers should also be able to gain significant extra business from the IoT.
